Ultimate Guide to Trading Systems: In-Depth Analysis of Eight Classic Frameworks

In the world of financial markets, an effective trading system often determines success or failure. Today, I will introduce the industry’s recognized eight classic trading systems. Most of these systems originate from the practical experience and writings of top global trading masters and are widely used in forex, futures, stocks, and other markets. Whether you are a novice just entering the market or an experienced veteran, you can find methodologies suitable for your trading style within these systems.

Turtle Trading System: The Pioneer of Breakout Trading

When it comes to classic trading systems, the legendary Turtle Trading System is unavoidable. In 1983, renowned American speculator Richard Dennis sought to answer an eternal question: Are great traders born with innate talent, or can they be cultivated through training? To find the answer, he recruited 13 beginners and taught them basic trading concepts along with his years of trading methods.

The results over the following four years shocked the financial world: these Turtle students achieved an astonishing average annual return of 80% compounded. This experiment proved that—using a simple yet effective trading system with clear rules—even completely inexperienced individuals could become excellent traders.

The core logic of the Turtle Trading System is extremely simple yet profound. When the price breaks above the highest point of the past 20 trading periods, it signals upward momentum and a potential entry point; when the price falls below the lowest point of the past 10 periods, it indicates a possible trend reversal and a stop-loss point.

In practical application, this system has two main versions: a short-term version (System One) based on a 20-day breakout, which is more sensitive; and a long-term version (System Two) based on a 50-day breakout, which is more robust. Because of its clear logic and explicit rules, many later trading masters have developed their own variations of Turtle-style trading systems based on this foundation.

Williams Gap Trading System: The Profit Code of Emotional Reactions

Larry Williams is the creator of the Williams %R indicator and one of the most famous contemporary futures traders in the US. He once turned $10,000 into $1.1 million within 12 months and won the Robbins Cup Futures Trading Championship.

The uniqueness of Williams’ gap trading system lies in its nature as a psychological trading approach aimed at capturing price jumps caused by market overreaction. The basic logic is: during a downtrend, prices fluctuate within a narrow range for 5 to 10 days, accumulating significant selling pressure; when the market gaps down sharply below the trendline, selling sentiment peaks. If the price then rebounds and closes above the previous day’s low, it indicates that market energy is about to reverse, and a new upward trend is building.

The execution rules are also clear: first, confirm that the closing price is 4% below the 5-day moving average, ensuring the signal occurs during a clear downtrend; second, the opening price should be 1% below the previous day’s low; finally, the close must rebound above the previous day’s low. Only when all three conditions are met does a buy signal trigger.

TD Price Range Trading System: Opportunities from Supply and Demand Imbalance

Tom DeMark served as a special advisor to major financial institutions like Soros and Goldman Sachs. He believes that the key to technical analysis is not whether a price level is overbought or oversold, but how long indicators operate in these states.

To accurately measure market buying and selling pressure, DeMark created the TD DeMarker II indicator. The innovation of this system lies in linking all price movements to specific supply and demand levels. The calculation is somewhat complex: the numerator combines two measures of buying pressure—subtracting the previous day’s close from the current high, and subtracting the current low from the current close; the denominator adds these values to the corresponding measures of selling pressure over the past 8 bars. This approach allows the system to more precisely capture shifts in buyer and seller forces.

Volatility Trading System: The Art of Moving Quietly Before the Storm

Laurence McMillan, a top expert in options trading and former employee at Thomson McKinnon Securities, emphasizes that the speed of price changes can itself predict large market swings.

Volatility is typically calculated using standard deviation, compared across different timeframes such as 10, 20, 50, and 100 days. The trading rules include three key elements: first, historical volatility shows a bearish alignment, meaning narrowing volatility often signals calm before a storm; second, calculating the standard deviation of historical volatility over 5, 10, 20, 30, and 100 days; third, the AC and AO indicators show a continuous decline over five days. When all these conditions are met, it indicates that the market is about to experience significant volatility.

Oscillation Trading System: Precise Capture of Extreme Reversals

Martin Pring is one of the most influential figures in technical analysis today, and he has received the Jack Frost Memorial Award from the Canadian Technical Analysis Association.

The core idea of the oscillation trading system can be summarized as “extremes lead to reversals.” When prices reach extreme oscillation points, reversals are often imminent. The trading rules are straightforward: calculate the ratio of the closing price to the 28-day moving average; when this ratio drops below -10, it indicates the price has moved far from the average, signaling a reversal. Traders can further confirm with volume oscillation indicators to verify convergence between price and volume, thereby increasing the win rate.

Derivative Oscillation Indicator Trading System: Advanced Application of RSI Triple Smoothing

Constance Brown, a master in securities analysis and founder of a well-known investment website, developed an innovative derivative oscillation system that improves upon the traditional RSI (Relative Strength Index).

This system enhances RSI signals through triple smoothing: first, calculate the 14-day RSI; second, compute a 5-day moving average of this RSI; third, take a 3-day moving average of the previous result; finally, find the difference between the second and third smoothed values and display it as a histogram. This multi-layer smoothing filters out noise, providing clearer trading signals.

Dolphin Trading System: Complete Framework for Trend Following and Right-Side Entry

The Dolphin Trading System embodies the philosophy of “trend following and right-side entry.” It employs a layered time-frame structure, applying different indicators at various stages to facilitate efficient decision-making.

First, traders select their primary trading session based on personal habits—preferably the session they are most comfortable with. The previous period of the primary session is used for trend judgment, and the next period for entry and exit.

For trend judgment, the system uses the MA26 moving average and MACD indicator. When the price is above MA26 and MACD Value > Signal > 0, it indicates a bullish market, suggesting a long position; when the price is above MA26 but MACD Signal > Value > 0, it indicates a retracement, prompting to close long positions and consider short entries; when the price is below MA26 and MACD…
